Question

我在rails 4.2.7应用程序中使用带有omniauth-facebook gem的Devise。我目前收到以下错误The action 'facebook' could not be found for Devise::OmniauthCallbacksController。我按照本指南https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview设置了应用程序。

我的文件如下所示，

的routes.rb

# easy routes for devise
  devise_scope :user do

    get 'login', to: "devise/sessions#new"
    get 'signup', to: "devise/registrations#new"
    # delete 'sign_out', to: 'devise/sessions#destroy', :as => :destroy_user_session
  end

  devise_for :users, :path => '', :path_names => {
    :sign_in => 'login', :sign_out => 'logout',
    :controllers => { 
      :omniauth_callbacks => "callbacks",
      registrations: 'registrations' 
    }
  }

devise.rb

config.omniauth :facebook, ENV['FACEBOOK_KEY'], ENV['FACEBOOK_SECRET'],
   callback_url: ENV['FB_CALLBACK'],
   :scope => 'email',
   :info_fields => 'email'

模型/ user.rb

devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, :omniauthable,
         :omniauth_providers => [:facebook]

callbacks_controller.rb

class CallbacksController < Devise::OmniauthCallbacksController
  def facebook
    # You need to implement the method below in your model (e.g. app/models/user.rb)
    @user = User.from_omniauth(request.env["omniauth.auth"])

    if @user.persisted?
      sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated
      set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
    else
      session["devise.facebook_data"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end

  def failure
    redirect_to root_path
  end
end

当我尝试通过Facebook登录应用程序时发生错误。

行动＆＃39; facebook＆＃39;找不到Devise :: OmniauthCallbacksController
